GtoPdb Ligand ID: 10916

Synonyms: Bactroban® | BRL-4910A | BRL-4910F | Centany® | pseudomonic acid
Approved drug PDB Ligand Antimalarial Ligand
mupirocin is an approved drug (FDA (1987), UK (1998))
Compound class: Synthetic organic
Comment: Mupirocin was initially isolated from Pseudomonas fluorescens [1]. It is an unsaturated ester of 9-hydroxynonanoic acid. Functionally, it binds to bacterial isoleucyl-tRNA synthetase and disrupts isoleucine incorporation into bacterial proteins. This is a unique mechanism of action.

Isoleucine utilization has also been shown to be an essential pathway in P. falciparum and a potential target for antimalarial drug discovery [3]. The Malaria tab on this ligand page provides additional curator comments of relevance to the Guide to MALARIA PHARMACOLOGY.
